SELF--PLAYING ATTACHMENT FOR KEY MUSICAL INSTRUMENTS.

SPECIFICATION forming part of Letters Patent No. 653,263, dated July 10, 1900. Application tiled July 17, 1899. Serial li'o. 724.064. (No model.)

T0 all whom it may concern:

Be it known that I, HARRY M. SALYER, a citizenof the United States, and a resident of the city of Newv Yorlq, borough of Bronx, in the county of,New York and State of New York, have invented certain new and useful Improvements in Self-Playing Attachments for'Key Musical Instruments, of which the following is a specification.

The object of myinvention is to provide a new and improved self-playing attachment for key instrumonts*such as pianos, organs, and the like-which attachment is simple in Construction, strong and durable, can easily be applied on any key instrument, and plays any desired melody, according to the tunesheet inserted, and produces all the various effects in music, .such as forte and piano, Works the pedals, varies the speed at which the music is to be produced, and which attachmentcan easily be adjusted to repeat the same melody any number of times automatically or can be adjusted to stop at the end of a tune, and which attachmentalso rapidly rewinds the music -isheet upon its original roller to permit removing it from the attachment,'so that another music-roller can be insei-ted. Y

In the accompanying drawings, forming a part of this specification, and in which likel letters of reference indicate like parts in all the views, Figure 1 is a general plan view of my improved self-playing attachment for key instru ments,the'attachment being shown as applied to the keyboard of a piano and the air-compressor used for working the attachment being shown in diagram. Fig. 2 is a side view of the,clainpingbracket on the under side of the attachment for holding the attachment over the keyboard. Fig. 8 is a vcr tical longitudinal sectional view of one of the key-operating plunger-s and the valve mechanism for the same. Fig. 4 is a. detail plan 4 view, enlarged, of tho pedal-operating mechanism. Figs. 5 and (5 are enlarged vertical l transverse sectional views on the lines 5 5 and 6 6 of Fig. l, respectively, both in the direction toward the right of Fig. 1. Fig 7 is an enlarged sectional'view of the key-levers, taken on "thelino 5 5 of Fig. 1. Fig. 8 is an enlarged plau'viowof the music-shoet rollers and the mechanism for operating the same, parts being broken away. Figs. 9 to 12, are sectional views of the controlling-cock. Fig. 13 is a sectional planvicw of the automatically-adjustable pressure-regulating valve.

Fig. 14 is aside view of the brake-pulley.

The entire mechanism is contained in a casing A, provided with a bottom which rests on suitable rabbots A2, Figr-l, of the keyboard-support, and from the under side of said bottom A' bracket-pieces A3 extend downward and below the keyboardsupport A of the pianoforte, the brackets A each being provided with a screw A5, by means of which the casing A can be clamped on thc pianofortecasing.

The casing A is provided'with aphinged cover A' andv with an intermediate horizontal partition or floor A?. On the intermediate floor oi' partition AT a bridge-piece l; is secured, near the longitudinal center line of the intermediate partition or floor A7 and in the direction of the length of the keyboard, which bridge-piece is preferably shaped conical in cross-section and is provided with a flattop B', Fig. 7, in which a series efducts or chan- 4secured en a rail li, attached to standards lV at the ends of the bridge-piece li. A shaft l is secured in the upper ends of the standards lli, and on said shaft a key-lever C is mounted for cach duct or channel L in the bridge-piece B, and the don'nu'aidly-extending free end C' of each liey-levcrrests upon the free end of the corresponding springstrip Bs, carrying on its under side the valve l for the corresponding duct or channel b.

Each key-lever C is provided at its free end with a beveled upwardly-cxtending lug C?, which several lugs C2 cach pass through a corresponding transverse slot c in a top plate C, secu red to the standards Bi", levers C being held in ,such positions that their lugs C1 reject through these slotsc un- 'der the action of their corresponding springs B43. `\A retaining-bar CG, grooved longitudinally omits under side for receiving the sevoral lugrsC'2 of the key-levers C, is hinged to the said keya standard b' and at its opposite end is provided with a latch b2 for engaging another standard bs for the purpose of locking said retaining-bar in place.

'lhc downwardly-extending front end C4 oi each key-lever C is provided with an arm C, extending toward the rear, and over the said .sevcrs arms Cf a half-round bar C extends in such a manner that when the several eylevers are raised and the half-round bar Cs is in such a position that its fiat side is in a horizontal plane the upper edges of the several arms Cf will rest against the said at side of the half-round bar, as'shown in Fig. 7,

A note-sheet of paper or other suitable material and provided with slots a', suitably spaced and arranged according to the music to be produced, rests upon the slotted plate CF, om which it is held by the retaining-bar C6, the,perforations a' being arranged in parallel rows extending in the direction of the length of the note-slidet, the rows being an equal distance from each other-'and separated a distance equal tothe distance between the lugs C2.

Each music-sheet is secured to a roller D, which is mounted removablybetween the standard D' and the hub of a cog-wheel D5,

mounted in a suitable standard Don the in `termediate floor or partition A7, and that end of the roller D engaging the hub of the cog wheel D is squared or inv any other manner so shaped as to turn with the cog-wheel D3.

The standard D is provided-with a longitu-` dinally-movable spring-bearing D2, of any well-known construction, forholdingthe lefthand end of .the roller D in such a manner that it may turn freely, at the same time permitting the ready removal of the roller, with the note-sheet thereon, when said spring-bearing Dl is pulled-out to the left. I do not show the details of the construction of this' spring-bearing, nor of the ends of the pivots of roller II), as such constructions are 4all well known apd not ofmy invention. 'lhe other end of the note-sheet is secured in any suitable manner on the playing-roller-D, which is mounted in suitable bearings D", Fig. 8, and is provided 'with means for attaching the end of the note-sheet to it, such means being shown in Fig. 1 and consisting of a pin (1.,-projc'cting into a 'slot d'in the note-sheet a; but

any other well-known contrivance may be usedfor'securing the end of the note-sheet in the playing-roller D5. The playing-roller D earries ,a;ogwheel D", secured to the shaft of shidplaying-roller D, which cogwheel D7 can-be engaged bya small cog-wheel D, mounted in a free end of swinging-arm D, mounted to on a shaft of the pinion DW, which pinion engages the wheel D3. The shaft E, en which said pinion Dl0 is secured, is a driven'shaft of a =`compressedair motor E' of any suitable construction. Acog-wheel E, mounted on asuitable standard, engages the cogwheel D,"s that when the arm D,

Fig. 6, is pushed'fto the.1ight the cog-wheel z Ds engages the cogfwhe'el Eand as the latter engages the cog-wheel Ds on the roller D the latter will be rotated and the sheet that has been wound upon the playing-roller D5 during the playingr of the instrument can be rewcuud back upon the original roller D by means of the said rrotor.' All that is necessary is to shift the cog-wheel DE out of engagement with the cog-wheel D7and into engagement with the rewinding cog-wheel E2; A centrifugal governor F, of any well-known construction, is provided upon its central shaft with a pinion F', engaged by the cogwheel F2 on the shaft E, driven directly by the motor, and said governor F is provided with a f rictionldisk F3, which rotates with the weights and moves lengthwise on the governor-shaft when said weights swing toward or from each other. A spring-brake leverF, attached to the' horizontal partition A7, extends upward at the side of the friction or brake disk F, and the friction-lever F can be pressed against the friction-disk F3 by two wedges F5 and F6, which can press laterally on the lever F, the wedge F6 resting against the beveled inner end part Flo of an elbowlever F7, pivoted on a standard F, its other end resting against au adjustable screw F9 in the standard F on the partition A7, which screw can be turned by means of a handle F"-, provided with a pointer F.

The plnngers for operating the keys and other parts of the mechanism, and which are all of one and the same construction and clearly shown in section in Fig. 3, will now be described. Compressed air is conducted into a chamber G, with which one or more of said plungers may be connected. 'lhe piston in the cylinder Il" is provided withasuitable packing H', and a'piston-rod Il, secured to the piston, extends through a hole in the outer head of the cylinder, whereby the piston-rod is guided. Said piston-rod may operate any suitable mechanism or it may carry a head Il' for striking a key, and which head is provided with a rubber, felt, or other pad H5. 'lhe outer head of the cylinder is provided with a vent-aperture Il", and a helical spring U7, surrounding the piston-rod Il, serves for pressing the piston inward. At the inner end of the cylinder H2 and between the same and the chamber G a cylinder J is located, the axis of whichis at right angles to the axis of the cylinder liz, and this cylin- IOC der J contains a piston J', provided with a suitable packing J2, a helical spring J3 being interposed between the cylinder-head J and the piston J' and bearing on each. An aperturedl neck .l5 in the cylinder-head J is connected by a fine air-tube ln with one of the channels b in the bridge-piece B for a pur'
